LOOM FOB WEAVING CUT PILE FABRICS.

T 0 all whom it may concern:

Be it known that I, FREDERICK IV. R0- CHELLE, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Looms for Weaving Cut Pile Fabrics, of which the following is a specification.

The object of my invention is to insure the production of a straight and properly cut pile at that selvage edge of the cut pile fabric from which the pile wires are withdrawn. This object I attain by providing means for imparting inward pressure to the pile-forming loops at and near said selvage edge so as to preserve said loops in an upstanding position when the pile wire with its cutting knife is withdrawn from the row of loops.

In the accompanying drawing-Figure 1 is a plan View of sufficient of a pile loom to illustrate my invention, and Fig. 2 is a side elevation of the same partly in section.

1 represents the breastbeam of the loom from which projects forwardly an arm 2 which constitutes a support for those end portions of the pile wires 3 to which are attached the headsl, whereby said pile wires are withdrawn from the rows of pile loops which have been formed upon them in the operation of the loom, the opposite end of each wire carrying a knife, which, as the wire iswithdrawn, cuts through the tops of the loops formed over the wire.

I Atand near that selvage of the woven web from which the pile wires are drawn, the pile loops have no lateral support, consequently they are likely to be bent downward or otherwise displaced by the thrust of the knife upon them with the result that an irregular or ragged selvage is presented. In order to overcome this objection, I mount upon the plate 2 a swinging presser blade 5 which is, by the action of a spring 6, coiled round its pivot pin 7, caused to press inwardly upon the end of that row of loops Specification of Letters Patent.

Serial No. 4&1,694.

from which the pile wire is about to be withdrawn, in order to provide lateral support for the end loop and those adjacent thereto, and thereby prevent the lateral displacement of said loops under the thrust of the cutting knife, the result being the production of a straight and uniform selvage and a properly cut pile extending completely up to the selvage.

IV hen it is desired to render the presser blade 5 inoperative it may be so adjusted that a pin can be passed through an opening 10 formed in the blade and through a like opening 11 formed in the arm 2, these openings being so disposed that when the pin has been passed through them the inner edge of the presser blade will be free from contact with the pile loops at the selvage of the web.

I claim:

,1. A loom for weaving cut pile fabrics, having a presser for acting upon the pile loops at that selvage of the fabric from which the pile wire is withdrawn, and serving to support said loops against the thrust of the cutting knife.

2. A loom for weaving cut pile fabrics, having an arm for supporting the pile wires, and a presser blade carried by said arm and pushing inwardly upon the pile loops at that SGlYflgG of the fabric adjacent to said arm.

3. A loom for weaving cut pile fabrics
